This is because different genes are switched on or off in different cells.
For example, the cells which develop into red blood cells have the gene for making hemoglobin (the red, oxygen-carrying pigment) switched on. Other cells have this gene switched off.
Cells form new cells with identical genetic composition through mitosis. This essentially involves the cell producing enough resources for two cells and then splitting it's membranes into two separate and distinct bodies.
Body cells undergo mitotic cell division so that each daughter cell is genetically identical to each parent cell and to all other body cells.
By definition, all human cells are animal cells. Different cells look different from others, no matter the organism. A human nerve looks almost identical to a nerve from a chimp, but a human nerve looks nothing like a cell from a chimp's muscles.
No, different cells in the body have unique structures and functions based on their specific roles. For example, skin cells are different from nerve cells in both appearance and function. Each cell type is specialized to perform specific tasks within the body.
the DNA should be the same in all cells as long as they part of the same organism.
No they don't
Mitosis results in two identical daughter cells, each with the same number of chromosomes as the parent cell. These daughter cells are genetically identical to each other and to the original parent cell.
no
No, not all human cells are alike. Cells are specialized to do a certain job. For example, a nerve cell is different red blood cell because they have different jobs to do. They look different, have differentnumbers of certain organelles's, and they are not all alike.
No, all cells do not look the same. Cells can vary in size, shape, and function depending on their specific role in the body.

The first cell to form in fertilization is the zygote. The zygote undergoes cell reproduction in order to form a multicellular embryo, in which all of the cells are genetically identical to the zygote. All of the body cells in the new offspring will, in theory, be genetically identical, unless uncorrected mutations occur.
Mitosis occurs in all somatic cells of the body, which are any cell that is not a sex cell. It is the process by which a single cell divides to produce two genetically identical daughter cells with the same number of chromosomes.
